CarComplaints.com Notes: The fourth generation Grand Cherokee took the relatively trouble-free run of the 3rd-generation and flipped the script.
From 2010 to 2011, complaints about the vehicle not starting increased 10-fold. In fact, the 2011 model year is riddled with engine problems and a defective TIPM might be to blame. The TIPM (Totally Integrated Power Module) distributes power to all the eletrical components in the vehicle, so when it starts acting funny so do numerous other components in the car. Orders for new TIPMs were so abundant that parts became scarce, prompting a class-action lawsuit claiming Chrysler ignored this obvious defect.
By 2012 complaints dropped back down by about 80%. Needless to say, if you see a used 2011 Jeep Grand Cherokee on a lot just keep walking.
Driving in the rain and the wipers just quit. Not cool. Also, another issue related to the Totally Integrated Power Module. Took it to a trusted mechanic. He said it was not the wiper motor, the TIPM is bad and needs to be replaced. Took it to the local Jeep Dealership, they put it on the diagnostic machine [to the tune of $80+) and said the TIPM checked out OK, I need a new wiper motor. Hmm. Asked them about the doors unlocking by themselves and not locking at different times. They couldn't answer. Told them to order the wiper motor, I kind of need wipers. Four days later, the wipers just started working again, on their own. Stupid TIPM! Chrysler/Jeep needs to replace that thing to keep the customers coming back. Cost to replace the TIPM? around $1,100 - $1,200.
